Answer:
outer trophectoderm layer (TE. trophoblast), an inner cell mass (ICM, embryo blast) and a blastocoel (fluid filled cavity)
The blastocyst is distinguished by the blastocoel, trophoblast cells, and inner cell mass.
What is blastocyst?A blastocyst is composed of an inner group of cells surrounded by an outer shell. The embryo will be formed by the inner group of cells.
Stage 3 begins when a cavity appears in the morula and ends when the embryo makes contact with the endometrial lining of the uterus and the zona pellucida is shed. Free blastocysts are stage 3 embryos.
Day 3 embryos are called "cleavage stage" embryos. The reason for this certification is that the embryo's cells are dividing (or cleaving), but the embryo is not growing in size.
The blastocoel, trophoblast cells, and inner cell mass distinguish the blastocyst.
Thus, these are the 3 parts of the blastocyst.

Explanation:
While dry cleaners are small businesses, they generate relatively large volumes of hazardous substances. EPA estimates the average dry cleaner generates 660 gallons of hazardous wastes a year. Unlike petroleum contamination which may break down over time by naturally - occurring bacteria in the environment, the chlorinated solvents that are used by dry cleaners are resistant to biodegradation. As a result, groundwater contamination from dry cleaners has a greater potential to migrate off-site which can be problematic since dry cleaners are often located within proximity to residential neighborhoods. Indeed, a 2002 Florida study found that dry cleaner contamination had migrated off-site at 57 percent of the contaminated sites. Due to these types of environmental hazards when commercial land is sold require a Phase 1 Environmental Assessment according to the Comprehensive Environmental Response, Compensation and Liability Act.
Why would the type of monitoring required as part Phase 1 Environmental Assessments be important if a dry cleaner was being sold?
Group of answer choices
This type of monitoring will allow the government to only sell land to businesses that have environmentally friendly practices.
The monitoring will allow the government to determine which type of business is better for the environment so dangerous businesses can be closed.
The monitoring will indicate any environmental damage done that should be remediated prior to selling the land.
The monitoring prevents the land from being resold to any dry cleaning businesses which can be damaging to the environment.
Answer:
This type of monitoring will allow the government to only sell land to businesses that have environmentally friendly practices.
Explanation:
This type of monitoring will allow the government to know about the businesses that causes pollution in the environment and the government is responsible to sell the land to those businesses that have used the methods which is environmentally friendly. The environmental friendly practices reduces the damage occur to the environment from human activities so the government must do monitoring of businesses.
While volunteering at a hospital, Alex learns that there are several different human blood types and they are determined by alleles. For example, a person with an allele for type A blood and an allele for type B blood will have type AB blood. Alex asks a nurse if blood type A or B is dominant. What answer does the nurse give him?
Answer:
They are codominant
Explanation:
There are 3 different alleles: IA, IB and i - IA and IB are codominants, i is recessive. Codominance means neither allele can mask the expression of the other and both alleles A and B are expressed in the blood type.
Blood type A and Blood type B both are dominant if allele A or allele B present with the O allele, however, they show codominance if they present together.
The human blood group system is known as the ABO blood group system that exhibits codominance. Following are the characteristics of this blood group system:
The system consists of three alleles A, B, and O.Both A and B are dominant in relation to O, and therefore blood group A or B can have the genotype AA or AO or BB or BO respectively.If both A and B are present together then they show codominance and have the genotype AB.Thus, the correct answer would be - both A and B are dominant if allele A or allele B present with the O allele, however, they show codominance if they present together.

2. animals eat plants and produce carbon dioxide and water how do you animals affect the amount of carbon in the earths atmosphere
Animals eat plants and produce Carbon-di-oxide. Due to this, the concentration of carbon increases in the Earth's atmosphere by the carbon cycle.
What is the carbon cycle?The carbon cycle is a biogeochemical cycle in which the exchange of carbon between the environment and the organisms occurs.
Plants are producers, they absorb carbon-di-oxide from the environment, and by the process of photosynthesis, they convert it into an organic molecule (glucose). When these plants are consumed by consumers, carbons enter the food chain. It transfers from primary consumers to secondary consumers and then tertiary consumers.
When the consumer respires, carbon is released into the environment in the form of carbon-di-oxide. When these animals die, their bodies decompose and carbon is absorbed again into the atmosphere.
Thus, this is how animals affect the amount of carbon in the atmosphere.

What is the significance of crossing over?
Answer and Explanation:
Crossing over is the switching of genetic material (DNA), which occurs in Prophase 1.
This all happens in Meiosis, which is the process of the formation of sperm and egg cells.
The paired chromosomes from each parent align so that similar DNA sequences from the paired chromosomes cross over one another.

How does cytokinesis in animal cells differ from cytokinesis in plant cells?
Answer:
Cytokinesis occurs differently in animal and plant cells. In animal cells, the plasma membrane of the parent cell pinches inward along the cell's equator until two daughter cells form. In plant cells, a cell plate forms along the equator of the parent cell.

Farmer Carroll breeds his black-colored dog and his golden-colored dog every spring to sell the puppies. Golden color is recessive to black. The most recent litter of puppies included 4 black and 4 golden. What most likely is the genotype of the black dog?
Answer:
Bb
Explanation:
If you use "b" to represent golden allele and "B" to represent the black allele, then crossing a Bb and bb dog will result in a 50/50 chance of they offspring being black or golden. Since half of the litter is black and the other half is golden, the black colored dog has a Bb genotype.
An allele is the alternative of the genes present for a character or a trait. The genotype of the black dog will be Bb.
What is a genotype?A genotype is a genetic information contained in a cell that passes from generation to generation.
The allele of golden-colored dog = b
The allele for black-colored dog = B
The genotype of the black and the golden litters are 1:1 or 50% each as 4 puppies are black and another 4 are golden.
If the parents having Bb and bb are crossed then only there is a chance that the 50% offspring will be black and golden. For an offspring to be 50% black the genotype of the parent must be heterozygous.
Therefore, the genotype of the black dog will be Bb.
